| | ====Ubuntu==== | | ====Ubuntu==== |
| − | 1. Clone Bsp project from Github
| + | |
| − | | |
| − | | |
| − | 2. Execute "./build.sh", to build your own uboot and kernel.
| |
| − | [[Image:R2_build_sh.png]] | |
| − | | |
| − | 3. After finish built, Execute "cd SD", plug your Ubuntu TFcard in PC.
| |
| − | | |
| − | 4. Execute "bpi-update -c bpi-r2.conf -d /dev/sdX", to update the compiled kernel to your TFcard.
| |
| − | | |
| − | 5. If you want to install Ubuntu on EMMC, follow these steps：
| |
| − | * Program ubuntu image to SD card
| |
| − | * Install this SD to R2 board and boot from SD
| |
| − | * Enter the Uboot prompt, and run command emmc pconf 48 to change Partition config of EMMC
| |
| − | * And then run command reset, let it boot to OS
| |
| − | * Enter the system with username pi or root
| |
| − | * Run command
| |
| − | echo 0 > /sys/block/mmcblk1boot0/force_ro to enable /dev/mmcblk1boot0 write mode`
| |
| − | * To write preloader to EMMC by running command:
| |
| − | "bpi-bootsel BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz /dev/mmcblk1boot0" where BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz is the preloader for emmc, please download it from link：https://github.com/BPI-SINOVOIP/BPI-files/blob/master/SD/100MB/BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz
| |
| − | | |
| − | * To copy ubuntu image to EMMC:
| |
| − | unzip -p <XXX.img.zip> | pv | dd of=<device> bs=10M status=noxfer
| |
| − | or
| |
| − | bpi-copy <XXX.img.zip> <device> where the XXX.img.zip is ubuntu image we can get it from http://www.banana-pi.org/r2-download.html 40, and where should be /dev/mmcblk1.
| |
| − | * power off
| |
| − | * remove SD & power on
| |
| | | | |
| | ====OpenWrt==== | | ====OpenWrt==== |
| − | 1. Clone OpenWrt project from Github.
| |
| − | * Execute "git clone https://github.com/garywangcn/bpi-r2_lede.git"
| |
| − |
| |
| − | 2. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.
| |
| − |
| |
| − | 3. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/.
| |
| − |
| |
| − | 4. Use "make menuconfig" to configure your image.
| |
| − | * Choose "Target System" to config as "MediaTek Ralink ARM"
| |
| − | * Choose "Boot Loaders" to config as "u-boot-bpi_r2"
| |
| − |
| |
| − | 5. Execute "make -j1 V=s" to build your own OpenWrt image.
| |
| − |
| |
| − | 6. After built, we have two ways to install image.
| |
| − | (1) Plug your TFcard in Ubuntu PC, and enter to "build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/",
| |
| − | you will find two images:
| |
| − | * mtk-bpi-r2-EMMC.img
| |
| − | * mtk-bpi-r2-SD.img
| |
| − | (2) Write image to TF card, execute "bpi-copy if=mtk-bpi-r2-SD.img of=/dev/sdX"
| |
| − |
| |
| − | (3) If you want to install image to EMMC, We need another system which is running on SD card to program EMMC image to EMMC, please follow below steps to do:
| |
| − | * Copy EMMC image to a running system which is from SD card
| |
| − | * Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0 (assume /dev/mmcblk0 is for EMMC)
| |
| − | * Unlock EMMC boot0 block: echo 0 > /sys/block/mmcblk0boot0/force_ro
| |
| − | * Program preloader to EMMC boot0 block: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1
| |
| − | * Change the Partition configurion of EMMC is 48h: reboot the system which is running SD, and enter the U-boot command line, run command emmc pconf 48 (for this steps, we can change partition configuration in userspace by using mmc-utils,see more information in BPI-R2 OpenWrt(LEDE) Souce code : 2018-04-11)
| |
| − | * Power off, remove SD card, and then power on R2 board
| |
| − |
| |
| − | 7. This step is for upgrade, if you don't want to install image after you built, you could use runtime upgrade.
| |
| − | * Copy "bin/targets/mediatek/32/lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" to R2 board which is running OpenWrt system(no matter where(SD or EMMC) it boots from), and then run command "sysupgrade lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" to update both kernel and rootfs.
